Stackoverflow without recursion

Hi, I had posted earlier with an overview of my StackOverFlow Error problem. Now I have got some clues in this. The servlet is throwing a Stackoverflow error at Properties.getProperty() method. I know that stackoverflow occurs as a result of recursions. But I am not making any recursive calls in my code. I don't know why this error is bugging me. The code segment and the exceptions are listed below:

The exceptions:

Any clues will be appreciated. :roll:

Did you debug the application.

Why is this being printed so many times

Are you sure it's happening there ?
Is there any other places you are using Properties, using the following constructor ? Properties(Properties defaults)

I agree that it must be some other call that's causing this problem, but I don't think this is your actual code in the first place. Note that this line of code wouldn't even compile:

From the API documentation for Properties:
A property list can contain another property list as its "defaults"; this second property list is searched if the property key is not found in the original property list.
So if you created a Properties object that was its own default, and you searched it for a key it didn't contain, what would happen?

Yep, that is why I asked if he was calling using Properties(Properties defaults) somewhere else
I agree. Here's the link:
